preparation example Construction

[0057] According to the second aspect of the present invention, the present invention provides a method for preparing biomass fuel, comprising the following steps: mixing crushed straw, sawdust and fallen leaves with sludge and edible fungus residue, and drying to obtain biomass fuel.

[0058] The preparation method of biomass fuel provided by the invention has easy-to-obtain raw materials from waste, low cost, simple preparation method, easy control of operating parameters, low energy consumption, good molding effect of the prepared biomass fuel, and is not easy scattered.

[0059] In a preferred embodiment, molding is carried out at 25-27°C after said drying step to obtain biomass fuel.

[0060] Wherein, the molding temperature may be, for example, but not limited to 25°C, 26°C or 27°C.

[0061] The molding temperature affects the molding effect of the biomass fuel. The molding temperature is controlled at a suitable temperature. The molding effect of the biomass fuel is g...

Embodiment 1

[0071] This embodiment provides a kind of biomass fuel, comprising the following raw material components in parts by weight: 50 parts of rice straw, 50 parts of wheat straw, 30 parts of corn straw, 30 parts of apple tree chips, 30 parts of pear tree chips, apple tree chips 60 parts of fallen leaves, 25 parts of swamp sludge and 13 parts of edible fungus residue.

[0072] Among them, the water content of rice straw is 5%, the water content of wheat straw is 5%, the water content of corn straw is 5%, the water content of apple wood chips is 5%, the water content of pear wood chips is 5%, and the water content of swamp sludge 30%.

Embodiment 2

[0074] This embodiment provides a kind of biomass fuel, including the following raw material components in parts by weight: 40 parts of rice straw, 40 parts of wheat straw, 40 parts of corn straw, 40 parts of apple tree chips, 35 parts of pear tree chips, apple tree chips 75 parts of fallen leaves, 20 parts of swamp sludge and 11 parts of edible fungus residue.

[0075] Among them, the water content of rice straw is 2%, that of wheat straw is 7%, that of corn straw is 7%, that of apple wood chips is 2%, that of pear wood chips is 7%, and that of swamp sludge 25%.

Abstract

The invention provides a biomass fuel and a preparation method of the biomass fuel, and relates to the technical field of new energies. The biomass fuel comprises the following material components byweight: 110-150 parts of straw, 50-80 parts of saw dust, 50-80 parts of fallen leaves, 19-31 parts of sludge, and 10-17 parts of edible mushroom dreg. The provided biomass fuel takes the straw, the saw dust, the fallen leaves, the sludge and the edible mushroom dreg at certain proportion as the main raw materials, the various raw materials are from wastes, are mutually matched, and are fully burnt, the combustion heat value of the biomass fuel is 3500-4000 kcal / kg, the water content is less than or equal to 5%, the emission of the burnt waste gas is as follows: the NO2 is less than or equal to14.0 mg / m<3> (trace amount), the SO2 is less than or equal to 46 mg / m<3>, the smoke is less than or equal to 127 mg / m<3>, the emission is far lower than the national standard and is negligible, and the environment protection reaches the standard.

Description

technical field [0001] The invention relates to the technical field of new energy, in particular to a biomass fuel and a preparation method thereof. Background technique [0002] With the continuous shortage of energy and the rising price, biomass fuel has gradually entered people's eyes. Biomass fuel can replace gasoline and diesel produced from petroleum, and is an important direction for the development and utilization of renewable energy. Biomass refers to various organisms produced through photosynthesis using the atmosphere, water and land, that is, all living organic substances that can grow, including plants, animals and microorganisms. Biomass fuel is the processing of biomass into solid fuel (commonly known as "straw coal"). Biomass fuel is a modern clean fuel that uses new technology and special equipment to compress and carbonize various agricultural and forestry crop straws. It can solve the basic living energy in rural areas and increase farmers' income, and ...
